$2$a$.$ Briefly describe Javacc as an example of compiler compiler.

$2$b Given a simple database of results processing, the database consists of tables for

COURSES, STUDENTS, and RESULTS. The COURSES table lists pertinent data for

each course such as the course title and course code. The STUDENTS table lists

data such as matric number and names of students. The RESULTS table lists

pertinent data for each result obtain by each student. It should be possible to issue

queries against this database such as:

student $=$ "Ogundeji Stephen" and course $="$csc$533"$ and course $="$csc$306"$

$($student $=$ "Ogundeji Stephen" and course$="$csc$533")$ or course$="$csc$306"$

student $="$ Ogundeji Stephen $"$ and $($courses$="$csc$533"$ or course$="$csc$306")$

i$.$ Create a context free grammar file as input which will enable JavaCC to generate

a parser for the above query.

ii$.$ Discuss the possible output files produced by

Javacc for this problem
